- XNL-k Series
- Open-Type Orbital All-Position Welding Machine
This welding torch is specially designed for tube-to-tube TIG welding, suitable for carbon steel and stainless steel pipe butt joints/pipe flange fillet welding. It supports fusion welding or filler wire welding with an external XB50 head featuring AVC (Arc Voltage Control) and OSC (Oscillation Control) functions. Integrated with a wire feeder, it is compatible with the XNL-M400 digital programmed control welding power supply to achieve precise orbital TIG welding for tube/tube applications, ensuring high repeatability. Widely used in industries such as chemical, food, pharmaceutical, engineering installation, boilers, military, and nuclear energy.
